TO WHOM IT MAY CONCERN:

Be it known that I, NIRAM RUSSELL, of Harrison, Hamilton county, Ohio,have invented. a certain new and useful Earth-Conveyer; and I-herebydeclare the following to be a full, clear, and exact descriptionthereof,

referencebeing had to the accompanying drawings, making part of thisspecification. v

My invention relates to an cartheonveyer adapted to be used inexcavating-operations, the conveyer being so arranged as to deliver thedirt, sand, Ste., taken from the cutting, into cars or wagons,`which maybe situated either above or,bclow the level ofthe cutting In theaccompanying tlram'ings- Figure 1 is a side elevation of a convcyerembodying my improvements.

Figure 2 is a transverse section of the main part ofthe same.

Figure 3 shows a metallic flap to allow the escape of any dirt from theinside of the conveyor.

A A', B B', and C C','represent the main frame, of three sections, whichsupports the conveyer, and-the frames A A' and C C' are connectedtogether and held securely in position by the stanchions a a' and 'c c',whilst the two other frames B B' are pivoted to the inner ends of A A'and C C' by the bolts b 6' btb'f', The central section being thuspivoted to the two outer ones, enables either end of the frame to beelevated or depressed, so as to deliver the sand, 35e., either above orbelow the level of the cutting. Iournalled iu the outer. l

ends of the beams A' and C' are two drums, D and E, around which passesa chain, F, to which is attached a series of slats, ff, thus forming anendless carrier upon which the earth is conveyed away from theexcavation. The endless carrier is supported at suitable distances bythe rollers G, which runvupon the upper tracks, d d' 01"4 and the lowerones, e e' e". Upon the carrier is a hinged ap,f, of metal, which swingsopen once 4in every revolution ofthe carrier, and allows any dirt whichmay have collected inside the slats to drop out, the said Hapgravitating again to a closed position. The outer end of the beam C isprovided with an adjustable bearingbar H, having two depressions L z',and said bearing-bar has connected to it by thehook I a frame, J, whichsupports an endless carrier, K, constructed similarly to the uppercarrier Ff. The carrier K is propelled by tbe sand, 82e., which fallsupon it from the upper carrier F, and this frame can beso arranged as todeliver the sand into either compartment of a car, by simply causing thehook I to enga-ge with eitherot` the depressions L or h ofthebearing-bar H. The said bar H is pivoted in the cross-piece L, and restsin one of several notchesv in the u er side of the cross ieee M, thusadmittin of a lateral ad`ustment b movin from one notch to PP P S .l .Yg

another. The upper carrier F can be propelled by either hand, horse,steam, or any other convenient power`- and the frame ofthe conveyer canbe made in any number of sections.

I claim herein as new and of my inventionf- 1. The arrangement ofthejoiuted frame A A', B B', C C', endless carrierf, and pivoted Hap f',as herein described and for the purposes set forth. 2. In combinationwith the above parts, I claim the adjustable bar II, and adjustablecarrier K, as and for the purpose set forth. l

In testimony of which invention, I hereunto set my hand.
